David Karp, 85 cofounder of the Hills of Winchester, wholesale speciality bakers, died Sept 13 at the WashingtonHospital Center.

He and a brother, Julius, had established the firm in Brentwood in 1951. Its products are sold in stores and through catalogues in this country and abroad.

Mr. Karp had remained active in the business until recently becoming ill.

He had been active for many years in the Mishkam Torah Congregation in Greenbelt, which has the Karp Family School named in his honor.

In 1975, when Rabbi Kenneth R Berger of Mishkan Torah heard that Mr Karp was 83, he informed Mr Karp that it was possible for him to have a second bar mitzvah, but only if he promisedto study his Haftorah.

Mr Karp studied well and on Oct.4 of that year celebrated a simcha. He was the first member of Mishkan Torah to have a second bar mitzah. Others have followed in his steps.

Born in New York City, Mr Karp followed his father into the bakery business. he lived and baked in Englewood, N.J., Brooklyn, N.Y., and Stamford, Conn, where there is still a Karp's Bakery.

He and his brother moved to this area with their families in the early part of 1951 and briefly operated the Sheridan Bakery before establishing the Hills of Westchester.

Mr Karp lived in Hyattsville.

In addition to his brother, Julius, also of Hyattsville, he is survivied by three sons, William, of Hyattsville, Jack, of Fairfield, Conn., and Charles, of Stamford; three sisters, Dorothy Levine and LillianVogel, both of Norwalk. Conn., and Lottle Spencer, of Long Island. N.Y., seven grandchildren and 11 great-grandchildren.

The family suggests that expressions of sympathy may be in the form oif contributions to the David Karp Memorial Fund at Mishkan Torah
